Mystical Lake Hides Sunken City

Inside the National Park Bannf in Canada there is a glacier Lake Minnewanka which hides a sunken city since the 19th century.
This lake in Alberta on the surface looks like any other lake. It has wonderful nature, its depth is 142m and it spans over 20 square miles.

However many of the visitors doesn’t know that this lake hides a city called Minnewanka Landing from the 19th century that has been flooded.
The city has had four avenues, three streets, few houses, hotels and restaurants.
